At Purified Air we supply a range of passive filtration that can be used both in conjunction with our powered units or as standalone filters dependant on the situation.
We now supply Sitesafe carbon filters, these innovative carbon units measure 594x196x597mm, three combining to 594x594x597mm, directly replacing our original carbon blocks.
Their advantage is that they only weigh 18kg each against the 68kg of our original blocks. This takes the strain out of fitting and servicing, allowing only one engineer to complete the task where two had been previously required.
We use carbon filters to absorb malodours not particulates as this we leave to our ESP range, although that said these carbon filters will remove up to 95% of particles down to micron level in optimum conditions.
We supply a range of HEPA filters to suit your needs.
To qualify to be called a High-Efficiency Particulate Air or HEPA filter, the filter must be able to remove, from the air that passes through it, 99.97% of particles down to a sub-micron level of 0.3 microns. Our main use of HEPA filtration is the removal of smoke particles.
Our general purpose bag filters are manufactured using a galvanised steel header and are 100% thermally bonded. The pleated polyester filter media is flame retardant to CP413 (BS5588) and can be applied as a pre filter to carbon cells in malodour extraction, taking out oil and grease particles ahead of the carbon filter stage. These bag filters will remove up to 95% of particles down to 5 microns in optimum conditions.
Our new generation pleated panel filters are constructed using Aqua-Kote card frames making them highly resistant to tear, puncture and corner crush. Using the revolutionary electrostatically treated and hydrophobic Intrepid filter media from Kimberley Clark, our range of pleated panel filters have excellent bi-directional strength and high dirt holding capacities.
In optimum conditions these pleated panel filters will remove up to 95% of particles down to micron level and are used as stand-alone pre filters or as a pre filter to bag filters filtering oil and grease particles.
